ok i was thinking of running a mech. fuel pump but it is very tight around the water pump and i dont know if the mechanical will give me enough fuel. how big a job would it be to change over to a electric full pump?
There's no way running a double roller timing chain can affect which fuel pump you need. The fuel pump eccentric is bolted to the front of the camshaft just like any other so any pump made for a sb mopar will work with it. Only exception being something externally like a radiator hose interfering. You need to go to a different parts source because apparently the one your dealing with is just a computer parts jockey and don't know much about how a engine works.
BTW: I'm running the same one Woody is and it supplies my engine fine and I'm sure with sticky tires it'd break into the 12's easily.
